WINDOW.

SPECIFICATION forming part of Letters Patent No. 580,767, dated April 13, 1897. Application filed July 15, 1896. Renewed March 19, 1897. Serial No. 628,363. N0 model-l To all whom it may concern:

Be it known that I, JAMES CARPENTER, a' citizen of the United States, residing in the city of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Vindows, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to windows of the ordinary type, in which the sashes slide in Ways. The fitting of such sashes in the frames is a source of constant trouble. If they fit snugly enough to exclude dust and air in dry weather, they are sure to bind in damp weather, so as to make it extremely difficult to move them. On the other hand, if the fit is free enough to permit the sashes to be moved easily at all times and seasons not only will dust and cold air be admitted freely around the sashes, but each sash becomes a constant annoyance by reason of its rattling in every wind. If the wood of the sashes and frames is not thoroughly seasoned before they are assembled, all of these difliculties are enhanced. I have sought to overcome all of these difficulties and to provide a bearing of metal against metal which shall at all times form a tight joint but without binding, shall be inexpensive, shall be capable of being applied readily to any window, whether new or old, and shall in no wise injure the appearance of the window.

The construction in which I have embodied my invention will be described herein with reference to the accompanying drawings in which it is illustrated, and in which- Figure l is a perspective view, in vertical section, of a complete window embodying my improvements. Fig. 2 is a vertical section of the window-frame with the sashes removed. Fig. 3 is a horizontal section on the plane indicated by the line 00 w of Fig. 1. Fig. 4: is a perspective view of one corner of a sash.

In the drawings the window-frame is represented as composed, as usual, of side posts, one of which is represented at A, a head B, and a foot 0, and as having the usual parting-strip a, outer stop-bead b, and inner stopbead c, the latter forming vertical ways in which the upper and lower sashes D and D are adapted to slide vertically. To each vertical edge of each sash is secured by screws or otherwise 'a plate E, of thin metal, whose edges are turned inward toward the sash to form flanges e e. The body of the plate E .has a width slightly greater than the thickness of the sash, so that the flanges e e stand clear of the sash, whereby the wood may swell more or less without affecting the flanges. The said flanges, moreover, stand substantially at right angles with" the body of the plate, but preferably are flared outward slightly for a purpose to be referred to. In the guideway formed between the partingstrip and the stop-bead 011 one side or the other is introduced a metal bearing-plate F, which also has flanges ff.

As will now be understood, when the sash is in position the bearing-plate E, which is secured thereto, has its bearings between the flanges of the bearing-plate F, which is secured to the window-frame, so that there is always a bearing of metalupon metal, and

as provision is made, as already described, whereby the bearing'plates and their flanges are not affected by the shrinkage or the swelling of the wood, there is always a contact of such a nature between the sash and the frame as to insure the easy movement of the former. Moreover, as the flanges e e of the plate E flare outward slightly there is always maintained by the elasticity of the flanges such a contact between the fiangese eand the flanges f f as to insure a tight joint which will effectually exclude air and dust when the window-sash is in its closed position. Of course, as the necessity for a tight joint does not exist when the sash is in its opened position it is unnecessary that the bearing-plates F F should extend above or below the respective sashes when the latter are in their closed position. It will be observed that the flanges e e and ff of the plates E and F impart such stiffness to the plates themselves as to permit thin metal to be used, wherefore no special preparation of the window is necessary to permit my improvement to be applied thereto, and, as a matter of fact, it can be applied without any difficulty whatsoever to any ordinary window already constructed and in place, it being possible to set the stopbeads 11 and c farther from the parting-strip a, if it is necessary to secure additional room.

The top of the upper sash may likewise be provided with a-contact-plate G, having flanges g g to fit into and make close contact with a contact-plate I-I, having flanges h h, which is secured to the head of the window-frame. Likewise the bottom of the lower sash may have a contact-plate I with a single flange i to make contact with a similar plate J, having a single flange j, which is secured to the v sures a tight joint between them when the 1 window is'closed.

Itwill be readily understood that ifthe sash slideshorizontally corresponding changes-will be made in the bearing and contact pl-ates, but it is unnecessary herein to explainsuch changes, as they will be obvious when my improvements are understood.

The advantages of my improvements will be readily appreciated from the foregoin g description, and do not require to be enlarged upon at this point.

I claim and desire to secure by Letters Patent 1. In a Window, the combination with a frame having a grooved way for the sash and a flanged bearing-plate of metal secured in said grooved way, of a sash sliding in said grooved way and a flanged bearing-plate of metal of a width greater than the thickness of the sash secured to said sash and arranged to bear upon and make contactwith the firstmentioned flanged plate, substantially as shown and described.

2. In a window, the combination with a frame having a grooved way for the sash and a flanged bearing-plate of metal secured in said grooved way, o'f a sash sliding in said grooved way and a flanged 'bearing plate of metal secured to said sash and arranged to bear upon and make contact with the firstme-ntioned flanged plate, the flanges of the last-mentioned plate bein'g flaredoutwardl y, substantially as shown and described.

i This specifi-cation'signed and witnessed this 13th day of July, A. D. 1896.

JAMES CARPENTER.
